How work with two models and one form?
I've got two models ('Student', 'Instructor') and one form 'RegisterForm' with two selectors (for types). How can i save data from form in corresponding model if in class Meta field 'model' just for the only one model? I guess, my way is wrong, but so i asking. class Student(models.Model): username = models.CharField(max_length=30) first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) password = models.CharField(max_length=30) email = models.EmailField() passed_tests = models.IntegerField(default=0) available_tests = models.IntegerField(default=0) def __str__(self): return self.username class Instructor(models.Model): username = models.CharField(max_length=30) first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) password = models.CharField(max_length=30) email = models.EmailField() written_tests = models.IntegerField(default=0) def __str__(self): return self.username -
Django-Import-Export is not showing up in Admin interface GUI

Django Channels not sending reply message
Let me preface this by saying: I am a beginner at RabbitMQ and the concepts around it. I think I am starting to understand though. I currently have a problem with Django Channels. I had a setup where I was using the 'asgiref.inmemory.ChannelLayer' and I am currently switching to 'asgi_rabbitmq.RabbitmqChannelLayer' This all seems to work fine until I try to connect to the websocket from the browser. Nothing happens for a while (7 or 8 seconds) and then all of a sudden the websocket.receive gets triggered and the websocket disconnects. I think it is because the reply channel is not receiving my accept message.(or perhaps too late). routing: lobby_routing = [ route('websocket.connect', ws_test_add, path=r"^/testadd/$"), ] Consumer: def ws_test_add(message): print "TEST" message.reply_channel.send({'accept': True}) Group("testadd").add(message.reply_channel) Settings: CHANNEL_LAYERS = { "default": { "BACKEND": "asgi_rabbitmq.RabbitmqChannelLayer", "ROUTING": 'CouchGames_Backend.routing.lobby_routing', "CONFIG": { 'url': 'amqp://guest:guest@localhost:5672/%2F', }, }, } Log: 2018-01-31 20:00:21,141 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive 2018-01-31 20:00:21,144 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive 2018-01-31 20:00:21,157 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive 2018-01-31 20:00:21,157 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive 2018-01-31 20:00:21,163 - … -
django-python3-ldap Search Users belonging to Specific Group in Active Directory
I have django-python3-ldap included in my Django project, and I have it pointed at an Active Directory server. It connects to the AD server and returns a the username, first name, and hashed password to the auth_user table. How do I limit the search to only users in a specific AD group? Here are the relevant settings: LDAP_AUTH_SEARCH_BASE = "OU=******,DC=ad,DC=******,DC=org" LDAP_AUTH_USER_FIELDS = { "username": "samaccountname", "first_name": "givenname", "last_name": "surname", "email": "EmailAddress", } LDAP_AUTH_OBJECT_CLASS = "User" LDAP_AUTH_USER_LOOKUP_FIELDS = ("username",) LDAP_AUTH_FORMAT_USERNAME = "django_python3_ldap.utils.format_username_active_directory" LDAP_AUTH_ACTIVE_DIRECTORY_DOMAIN = "AD" LDAP_AUTH_FORMAT_SEARCH_FILTERS = "django_python3_ldap.utils.format_search_filters" I believe I need to use LDAP_AUTH_FORMAT_SEARCH_FILTERS to "and" conditions to the original search base, but I'm not sure exactly how to do so. I assume I need to write a custom format_search_filter, but I don't intuitively understand how it would cross-check with AD groups. -
Multiplying the value of two django integer fields

psycopg2.DataError: invalid input syntax for integer: "test" Getting error when moving code to test server
I'm running Django 1.11 with Python 3.4 on Ubuntu 14.04.5 Moving my development code to the test server and running into some strange errors. Can anyone see what is wrong from the traceback? I'm very new to linux and have made the mistake of developing on a Windows machine on this first go around. I have since created a virtualbox copy of the test and production servers to develop on, but I'm hoping I can salvage what's up on the test server now. I think my app is looking in the correct directory for this environment, but I am a Django, Python and linux noob. Any direction would be very helpful. Thanks!

Django DetailView additional checks based on object
Which method should be overridden to add additional checks and redirect accordingly? i.e. I've a DetailView for my product page, and if this product is not published (and brand has more products) I want to redirect to the brand page. I added this check to get method and I'm calling get_object() manually and then doing my checks, but in the end I'm also calling the super().get() which calls get_object() as well, this makes the SQL run twice. The solution I've found is overriding the get_object() method as following.. def get_object(self, queryset=None): if not hasattr(self, 'object') or not self.object: self.object = super().get_object(queryset=queryset) return self.object This doesn't feel right though, what is the best way to do checks without triggering get_object twice? My code that calls get_object twice looks like this: without the hack above. def get(self, request, *args, **kwargs): product = self.get_object() if not product.published: if product.brand and #more products from brand exists# return redirect(reverse('brand', args=(product.brand.slug,))) else: return redirect(reverse('pages:home')) return super().get(request, *args, **kwargs) -
Django Rest Framewrok Token Authentication for Custom User Model
I'm new to using Django Rest Framework. I have inherited a Django project that has 2 user models: mods.User tied to AUTH_USER_MODEL and players.Member. For reasons I can't get into here, they both inherit from AbstractBaseUser but involve different information, with only an email field common between them. I am trying to use token authentication for users in players.Member. I have created an endpoint /players_endpoint/register which successfully adds players to the database. However, after adding the player to the database, the json response comes back with Cannot assign "<Member: offworld_321>": "Token.user" must be a "User" instance. My create view is as follows: class MemberCreateView(generics.CreateAPIView): queryset = Member.objects.all() def post(self, request, format='json'): serializer = MemberCreateSerializer(data=request.data) if serializer.is_valid(): user = serializer.save() if user: token = Token.objects.create(user=user) json = serializer.data json['token'] = token.key return Response(json, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) I was following the tutorial here How can I make it such that upon registration, a player receives a token which will be used for authentication? -

Django Deployment Server serving Static Files with only uWSGI
im trying to get my Django App to run using only uWSGI. The project is not that big, so i would really prefer to leave nginx out. I just can't get uWSGI to show my static files though. I've gone through the settings multiple times and can't find the problem. I have the STATIC_URL set to 'module/static/' STATIC_ROOT set to '/module/static_files/' (i read somewhere that they should not be the same) and my uwsgi.ini looks like this: [uwsgi] module=Module.wsgi:application master=True http=:80 processes=4 threads=2 static-map /static= /module/static_files/ the projects file structure is set up in the following way: -- Project: ---init.py ---settings.py ---urls.py ---wsgi.py -- Logs -- module ---static ---static_files ---[... module template, model, urls etc] -manage.py -db.sqlite3 I can run collectstatic and generate all the static files in the correct folder. But when i run the uwsgi script, it wont work and gives me a 404 file not found for all static files. I would really appreciate any help, I've been stuck on this for an entire week now... (i have checked out Deployment with Django and Uwsgi but as far as i can tell, my static-map is set correctly) -

Django test client POST command not registering through 301 redirect
